Loopback Test Failure

NOTE: After making any repairs, perform BODY VERIFICATION TEST under VERIFICATION TESTS.

Using scan tool, record and erase DTCs. Turn ignition off. Wait 10 seconds. Turn ignition on. Operate power sliding door from open to full closed position several times if possible. Recheck for DTCs. If LOOPBACK TEST FAILURE resets, replace Power Sliding Door Module (PSDM). See POWER SLIDING DOOR MODULE under REMOVAL & INSTALLATION. If LOOPBACK TEST FAILURE does not reset, system is operating properly at this time. Check for intermittent poor connections or faulty circuits.
